Hey if you've already decided then I wont argue.
All I got are newspaper reports, eyewitness accounts, and historical analysis about why Macarthur didn't expect and chose to not prepare for China's invasion of Korea. Not only that, how he was so oblivious to the seriousness of the October catastrophe afterward that he proceeded to announce that the boys would be home by Christmas.
I am not saying that Mcarthur did not make some mistakes...war is a very hard task to general. Maybe you should try it sometime. What you did was overstate your case by saying he said it was impossible for the Chinese to get involved, and he did not...right?
